Simcom 7020G IOT module support? (m5 stack)

jenn · January 28, 2021, 5:05pm

Just wondering if anyone has used this yet? (with Hologram?)

Links below. Getting a new hologram sim card in the email later today, to supplement another esp32 project I did… This time, I’m trying to M5 stack module one for kicks… I use platform IO for arduino type stuff, or the expressif dev env.

I’ve used sim7000 stuff with Hologram before (here in the usa) and had wonderful results.

Thanks in advance!

## Description

This is a wireless communication module, integrated an **NB-IoT** M5311  module that produced by China Mobile. The dimension if M5311 is 16mm * 18mm * 2.2mm, which is very tiny, and gives convenience to the user of more flexible dimension requirement.  

package with LCC allows quick production through standard SMT, which provides a more reliable connection method and performance on the extreme environment. 

the power requirement of this M5311 module is down to 2.1V, AA battery supported, it can fully utilize the power of AA battery, to provide an extremely low-power-consumption solution for terminal devices.

M5311 provides abundant external interfaces and protocol stacks, support peripheral sensors, etc.

Based on M5311, we have offered extra hardware resources on NB-IoT Module, WUP, STA LEDs, 3 alternative UARTs, one power button, and 2 alternative antennae.
